On my ride yesterday when I stopped the Garmin 1040 it promptly reported, New maximum heart rate detected of 157 bpm. Uh, that was bogus, because in both Garmin Connect and Strava they reported that my maximum heart rate was only 133 bpm.
How can Garmin get something so simple like maximum heart rate, so wrong?
Garmin Tech Support using the Chat feature was totally useless, my chat guy Kurtis kept babbling about a proprietary algorithm for calculating maximum heart rate. He was so nonsensical I had to ask if he was a ChatBot or a Human.
